To all whom it may concern.

Be it known that I, IRA H. SPENCER, a citizen of the United States, and a resident of Hartford, in the county of Hartford and State of Connecticut, have invented a new and Improved Cleaning Apparatus, of which the following is a specification.

The invention relates to the class of devices specified and the object of the inven tion is to provide a device of this class having numerous novel features ofadvantage' and utility.

form, having a scar 19- W from the outer base section 14 by struts 20 One form of device in use of which these objects may be attained is illustrated in the '10 denotes legs or like parts upon which the base is supported. The legs and the base are constructed of any desired material, and of suitable ilorm for the special requirements for which the appa 'atus may be designed. In the form of construction herein shown, cars 11. having openings for the reception of studs 12, project radially from the base,

the studs passing freely through the open ings and being threaded at their ends to receive a blind nut 13. The base as herein shown. consists of an outer or peripheral section 14 and an inner section 15. The outer section is of annular form, having a groove 16 located between the outer and inner walls 17 and 18, and the cars 11 are preferably secured to the upper edge or rim of the outer wall 17.

' The inner section 15 of the base is of ring and being supported providing a space between the two sections, as plainly shown in Fig. 1. Grooves are formed in the bottoms of the inner and outer base sections for the reception of packing rings 21 and 22, as shown in Fig, 1 of the drawing, and the upper edges 23 and 2st I of the wall and partition of a pan 25 seat against these packing rings forminc a tightomt at this point. The pan 25 s dividedby the partition into outer and inner compartments, the inner receiving dirt direct from the turbine. and the outer receiving dirt from a screen to be hereinafter dcscri bcd. The pan is rcmovably secured in position as by means of links 27 pivoted to the base and engaging slots in cars 28 on the pan, thumb nuts or screws 29-holding the parts against accidental disengagement.

A shell 30, with its axis vertically arranged, is supported by the inner section 15 of the base, this shell extending from the base for a suitable distance to suit the requirements of the machine. A cup 31 is supported bv pipes 32 secured to the shell 30, and the; pipes 32 aii'ord a passage from inside the cup. A plate 33 located within the shell near the upper end forming a top for the turbine chamber, a neck 34 projecting from a central opening in this plate into an inlet char-iber 35 formed in the upper end of the shell around said neck and underneath a cap 36. This inlet chamber is located in what may be clled a dome 37 of the device and constituting that part of the shell projecting beyond an inclosing casing to be hereinafter described. The shell Ell) is preferably. formed-of sheet metal with an inner flanged ring 38 secured to the upper edge, and upon which the cap 36 rests; An inlet opening 39 for an inlet pipe 40 extends through the shell and /ring as show'h in Fig. 1 ot' the drawings. he annular space between the neck 34 and side of the dome or shell is occupied by drawers 41 of a shape to lit within said space, and of suitable size to meet the requirements of the device. Shields 42 extending from the side of the dome cover such space within the drawer chamber as may not be occupied by the drawers. Handles 43 serve as a means for removing and replacing the drawers. A flange 44 projects from the side of the shell at the base of the dome, this flange in fact definingthe base of the dome, and a lip 45 from said flange receives the upper end of an inclosing casing 46, upon which end said flange rests. This inclosing casing has an outlet 47 and is of proper size to he slipped into place from the top of the machine passing downward and with its lower edge resting within the outer wall 17 of the base of the device. A.-

tlange 26 is also secured to the shell 30 and a screen 66 depends trom this flange within the screen chamber 65 formed between the inclosingcasing; 46 and the shell 30. The

lower end ot'the screen may be secured in any desired manner as by means of a cord passing around the inner wall 18 and underneath a lip 59.

A motor 48 of any desired construction suitable to the purpose in huncl rests upon the cap 56. Openings extend through the meter base for the purpose ofsupplying e11 Within the motor-casing.

V n A bearing neck 01 pro yects from the cup bottom of the blades) located at intervals along the shaft, and deflectors 57, arranged.

in sets, are locatecl in the compartments tween the partitions and on the opposite side of thedisks from the blades 54, the cleflectors being curved and extending from the periphery of the compartment toward. the center of the communicating openings 5?) between the compartments.

The action of the compresses creates e condition within the turbine chamber favorable to it great inrush of air thereto, whiz" extremely unfavorable to the inainte of lubricant in the shaft bearing in b 51, as such injrush air under the conditions existingin the turbine ch21. .ber will occur through the bearing to e degree gem erned by the amount of space about the shaft and thus remove the lubricant inthiii beeriu I In order to evoicl this-objection the beering 52 is made cf wood or such other me.- teriel as will not require it lubricant to successful operation. By employing been ing of this kind the objections herein before mentioned with regard to i'ncinteining lubricants therein are. obviated and the clustentl dirt passing into the machine in great quantities is ell'ectually psreventecl from ge'- ting into the bearing encl being retained therein, which hearing it will be seen constitutes not only a bearing for the shaft 523, but also for the motor, the shaft in fact being exteudeiito form-the 'znotcr shaft, or the motor shaft being extentlecl to form the turbine shaft the turbine depending within the turbine-chamber, and its bearings locatecl at the upper encl 52 and 60.

In the operation, of the device a. etching tool 61 being applied ,tothe surface being cleaned, the action oi. the turbine-senses a flow of air at the intake of the tool through the hose 62 and into; the inlet chemher 35,thz*ough the neck 34 into the turbine chamber. The action of the fan creates -con-- clitions within the shell that cause a great. inrush of air, so that the flow through the inlet pipe .0 tangentially. to the inlet chamber is around the Walls of the inlet chamber, the particles of dirt being deposited by centrifugal action Within the drawers or re ceptncles 41. The lighter particles of mapass with the air through the turbine and under the action. of the last set of blades constituting a fan 63 in the turbine, are thrown off by the centrifugal action to the periphery of the separating chamber 64-, from which they fell by the action of gmvity into the inner compartment of the pan The air now containing only the very light particles of dust passes into the cup 31 through pipes 32 and into the screen chamber Where it passes through the screen end out at the outlet 4:? where the air is \J.) ieliveretl practically pure. The dust particles are thrown oil by centrifugal action and the form and location of the cup collects the practically pure air at the vortex of the Whirl, the location of the cup causing the air currents that have been thrown outward by centrifugal force by the action of the fans to be suddenly (livertetl and drawn to the center of the chamber and into the cup, the heavier particlcs of clirt being thus caused to be separated from the air currents and this hea ier portion of the dirt is, therefore, prevent-mi. passing with the air cur- I rent through the pipes 32.

The screen 66 may i e renclily freed from (lust by 'shel'aing it in any desired manner, the clust falling into the outer compartment oi? the pain :25, passing through the opening between the outer ei'u'l'inncr sections of the base. A portion of the dust will also be de- 10 nosited in groove 10 l? the outer section 01 the The can In J be easily removed. eiul emptied 0' le lie iter particles of clust o1" clirt "when required.

lncrcler to prevent large pieces of rags and aste or like material from entering the shell and interfer' with the fans, a guard 70 is located in the space between the upper edge of the neck 35: anal the-under surface of the 36. This guard is in the H5 form of net Work so that air Wi the lighter particles of dirt with which may be inipre neteil, may .ISS freely through the meshes.
